Abstract: The machine comprises a print table (8) and a print head (3) which are intended for the printing of characters on labels (11) borne by a continuous strip (10). The print head (3) comprises a pusher (32), a lateral stop (29) and two detention notches (30, 31), and the print table (8) has a rotary cam (33) with return prism (34) and cocking spring (35), having three lifts (38). Upon the typing, one lift is turned by the pusher (32) and the following lift comes laterally against the stop (29). When the print head rebounds, this lift engages in a notch (30) and holds the print head spaced from the print table. This arrangement is provided to prevent a second printing of characters on the labels as a result of rebound. In a variant, the rotary cam is replaced by a reciprocating bolt.

Abstract: The invention provides a radial friction bearing assembly, particularly for rotatably mounting the rolls of a paper or textile material processing machine, which will give a stable rotational movement without any vibrations and ensures that always an uninterrupted lubrication film is available, even at very low rotational speeds. A preferred embodiment of the bearing assembly comprises a stationary shaft member and an annular sleeve member rotatably mounted on the shaft member. The latter one comprises on its outer surface a plurality of equidistantially arranged longitudinal grooves which extend parallelly to the axis of the shaft member. A plurality of trapezoidally shaped recesses or pockets, having a substantially smaller depth than the longitudinal grooves, extend from and communicate with said grooves, the base edge of the trapezoid adjoining the leading edge of the longitudinal grooves. Between two adjacent recesses or pockets, a circumferential annular groove is provided which communicates with all longitudinal grooves. A lubricant, preferably water, is fed to the longitudinal grooves and circulates therein as well as in said circumferential grooves, said recesses and in a gap provided between the stationary shaft member and the rotating sleeve member.

Abstract: A static controlled reactance device is inserted in series with an AC electric power transmission line to adjust its transfer impedance. An inductor (reactor) is serially connected with two back-to-back connected thyristors which control the conduction period and hence the effective reactance of the inductor. Additional reactive elements are provided in parallel with the thyristor controlled reactor to filter harmonics and to obtain required range of variable reactance. Alternatively, the static controlled reactance device discussed above may be connected to the secondary winding of a series transformer having its primary winding connected in series to the transmission line. In a three phase transmission system, the controlled reactance device may be connected in delta configuration on the secondary side of the series transformer to eliminate triplen harmonics.

Filed: 1989-02-20
Abstract: The present disclosure describes flame-retardant, high-temperature resistant polyimide fibers, nonwovens made from said fibers, as well as the fibers and molded articles obtained after a heat treatment. A composite of such fibers is heated to a temperature in the glass transition range of the fiber, i.e. between 280 DEG  and 350 DEG  C. This heat treatment develops a contraction force of 0.3 to 1.1 cN in the fibers which results in a fiber shrinkage of between 20 and 60% and the formation of cohesive bonds. The fibers of the invention enable the manufacture of molded articles that are particularly strong, have a high temperature resistance and flame-retardant properties, while having a relatively low density.

Abstract: The invention relates to a method of applying a torque onto the cubital axis of an upper arm prosthesis for pivoting the forearm by means of a spring force, as well as to an elbow lifting device. The elbow lifting device comprises an upper arm member (1) which is connected in articulated fashion to a forearm member (2) via at least one cubital axis (3), pivoting of the forearm member being assisted by a spring element (6). The spring element (6) exerts a tensile force directly or indirectly upon the entry (17) to a gear (7) whose exit (18) engages on the inner end of a tensile member (9) whose outer end can be fixed on a fixing point (20) of the upper arm member (1) which defines a torque lever with the cubital axis (3). The force is transmitted by the gear (7) in such a way that the course of the torque acting upon the fixing point (20) of the upper arm member (1) as a function of the bending angle of the forearm member (2) is approximately parabola-shaped and shows its minimum values in the extended position from about 5 DEG  to 25 DEG , preferably 10 DEG  to 20 DEG  and at maximum flexion, and shows its maximum at about 90 DEG . <IMAGE>

Abstract: <B>MéTODOS E APARELHO PARA MISTURA DE GáS E LìQUIDO<D>. Método e aparelho aperfeiçoados para mistura e introdução de gás em uma grande massa de líquido. O aparelho suporta e gira uma pluralidade de elementos de descarga semelhantes a raio (484) abaixo da superfície do líquido. Os elementos têm superfícies de descarga perfuradas voltadas para cima (485) através das quais gás comprimido é liberado para cima para dentro do líquido. Preferivelmente, os elementos têm porções inferiores, não porosas. Para contrariar as forças de efeito de "bomba de sucção" ascendentes criadas pelos elementos giratórios, os elementos são inclinados com suas bordas avançadas mais baixas do que suas bordas traseiras. A inclinação dos elementos e a velocidade de rotação são equilibrados de modo que o ângulo de ataque resultante do líquido em relação às superfícies de descarga é zero ou ligeiramente maior, para cisalhar de forma eficiente e eficaz o gás emergente em bolhas de tamanho relativamente pequenas.
